The Model UHH-BTG wireless mobile wireless gateway transforms the wireless signal from any Dwyer Instruments universal handheld probe or module into a Bluetooth SIG wireless technology. Using this gateway, any iOS® Firmware version 5.X or later or Android® Firmware version 3.X or later smartphone or tablet can become the base instrument for measuring or logging. Once the gateway is paired with a phone or tablet, the Mobile Meter™ app or any other Dwyer Instruments approved apps can detect available probes or modules. Can detect probes or modules that are 50 ft away, or even farther, depending on the environment. Dwyer Instruments
